A 6.0 magnitude earthquake struck near Honaunau-Napoopoo on Hawaii's Big Island late Saturday, triggering rockslides across the South Kona area and cutting power to about 500 customers, ABC7 Los Angeles reported.

The quake posed no tsunami risk, but structural damage, rockslides and power outages swept South Kona. Kona Hospital reported minor damage with no disruption to patient services.

The earthquake struck at 9:46 p.m. local time and was centered 3.7 miles east-southeast of Honaunau-Napoopoo, according to the U.S. Geological Survey. Strong shaking spread across the Hawaiian island chain within minutes of the strike.

"The Pacific Tsunami Warning Center reports no tsunami threat at this time," the Pacific Tsunami Warning Center said. Officials also said there were no apparent effects on Mauna Loa or Kīlauea volcanoes in the wake of the tremor, according to ABC7 Los Angeles.

Multiple rockslides struck roadways and hillsides throughout South Kona in the hours following the quake. Kona Hospital sustained minor structural damage but continued operating without interruption, the County of Hawaii reported.

About 500 Hawaiian Electric Company customers lost power, with utility lines reported down in multiple parts of South Kona, according to ABC7 Los Angeles. Crews were deployed to assess damage and restore service.

Homes and structures across the South Kona area sustained scattered damage, authorities said. No injuries were immediately reported in the aftermath of the earthquake.

No injuries were immediately confirmed following the earthquake, and the Pacific Tsunami Warning Center maintained that no tsunami threat existed in the region.
